Even if you withdraw they'd still know that you used to have one. They are ok with dual intent, so no worries I would say. Going by their definitions, submission of EE profile is just an expression of interest and not application so we shouldn't have been worried at all. However, if the VO was incompetent, then you could have your application rejected. So best to disclose it. I didn't cos i was confused by the semantics. I didn't get any advice on this forum so I went ahead submitted additional information through the web form where I explained my confusion. I will find out when I get to know the outcome of my application. I think you'll be fine, just disclose it cos you never know how competent or well-trained the VO is
